Method Detail

convertGraphNodeToRDFNode

public static RDFNode convertGraphNodeToRDFNode(Node n,
                                                Model model)

tripleToStatement

public static Statement tripleToStatement(Model model,
                                          Triple t)

isValidAsStatement

public static boolean isValidAsStatement(Node s,
                                         Node p,
                                         Node o)

Determines whether a valid Statement can be formed from the given Subject, Predicate and Object

This function reflects the fact that the Triple API is flexible in allowing any Node type in any position (including non-RDF node types like Variable) and as such not all Triples can be safely converted into Statements

Parameters:

s - Subject

p - Predicate

o - Object

Returns:

True if a valid Statement can be formed

triplesToStatements

public static StmtIterator triplesToStatements(Iterator<Triple> it,
                                               Model refModel)

statementsToTriples

public static Iterator<Triple> statementsToTriples(Iterator<Statement> it)
